10 Things You Should Know About Dermaroller Micro-Needling

4th March 2015

Micro-needling is a cosmetic procedure I am regularly asked about by patients. I'll try to answer the most frequently asked questions about the treatment and its benefits.

Dermaroller at Karidis

  1. Micro-Needling is a minimally-invasive cosmetic procedure using collagen induction therapy (CIT) and uses a Dermaroller.
  2. A Dermaroller is a small, handheld rolling device covered with tiny needles. These needles penetrate the deeper areas of the skin without removing the top layer. The reason for this is to control injury underneath the skin’s surface, inducing the formation of new elastin and collagen fibres.
  3. As the body responds to the treatment the skin appears fuller, ultimately reducing the appearance of fine lines, wrinkles and improving skin texture. 
  4. The method is designed to treat a variety of skin conditions such as fine lines and wrinkles, acne scarring, photo damage and texture changes.
  5. The Micro-needling procedure is predominantly used for the facial area. However, it can also be applied to other parts of the body if required.
  6. To minimise pain and discomfort, a numbing cream is applied to the affected area prior to the treatment.  However, local anaesthetic may also be used for particularly sensitive areas.  In both cases pressure will still be felt, but this should not be painful.
  7. Results are seen within 6-8 weeks, and will continue to improve over time. For optimal results, it is recommended that the patient should return for a series of 2-3 treatments, with an interval of 6-8 weeks between each.
  8. After the treatment, patients may experience some redness, bruising and minor bleeding for 24-48 hours. Similar to sunburn, the skin will feel warm, tight and itchy for a short period of time but this will fade relatively quickly. For patients with sensitive skin, it may take up to a week to fully recover.
  9. Side effects of the treatment are minimal and will most likely include minor flaking or dryness.  Infections are extremely rare.
  10. The procedure is not suitable for those who have had radiation treatment within the last 3 months or for those who have used Roaccutane (isotretinoin). It is also not advisable for women who are pregnant or breastfeeding, anyone with open wounds (including cuts and abrasions), a skin condition, a history of keloid or hypertrophic scars or poor wound healing.

Thank you for working your magic and making me look years younger! Also a big thank you to your team for all their help and support. I love my new face!

Karolina is always a joy to work with - kind, considerate and very professional and creating an aura of trust. She makes the Ulthera treatment painless and that's not an easy task!

I have my Botox with Karolina. She is exceptionally knowledgeable and advises me on what would look good and not so good on my face. She is a person I can trust!

"I was very happy with my treatment experience. Mr Karidis , staff and facilities were excellent. I am very pleased with the results and would not hesitate to recommend Mr Karidis and his clinic."

"I am only three days into the recovery of my gynecomastia procedure, and already it has changed my life. I travelled from Cardiff to London to have this procedure and it was by far cheaper than having it done in my local area. Furthermore, Karidis' reputation exceeds expectations. I look forward to my follow up consultation so Karidis can see how he has changed my life. Communication from Karidis and his team - 5 star Professionalism - 5 star Results - 5 star."

For my first Velashape III treatment, Maxine made me feel really comfortable and explained exactly how the treatment would go and any after-effects I might have (I have had none). The process was smooth and painless and actually kind of relaxing. Most importantly, I can already see a MAJOR difference on the cellulite on my legs and butt. I am seriously impressed!

"My entire experience for an abdominoplasty and breast augmentation operation was faultless from a professional and caring team. I cannot recommend Mr Karidis enough from the consultation, in establishing what I wanted, to his skilled work. I am absolutely delighted with the results."

"A seven week recovery journey with a couple of little detours, but navigated with care by Mr Karidis, Suzi & Martina. Explanations, reassurance & advice given from first consultation, day of operation, day one post op. and at all subsequent clinic visits, along with a good dose of friendly chit chat & laughter, (Always a good medicine!). Thank you Mr Karidis & team. No regrets here."

Brilliant consultation... I was very impressed with my consultation with Mr Karidis. Mr Karidis made me feel very comfortable and answered all my questions.

Outstanding in every way This is my second breast augmentation with Mr Karidis - my first experience was amazing as were the results! Second time around and once again my experience was faultless. The whole team are amazing from front of desk and Rose, to the lovely nurses pre and post-op! The after care given, which is also important, is second to none and I cannot recommend Mr Karidis enough. Thank you so much for all you have done for me and giving me back my confidence!
